Silent Knight SK-PHOTO-T-W Smoke Detector w/ Thermal Sensor (White)

The Silent Knight SK-PHOTO-T-W is an intelligent addressable plug-in photoelectric smoke detector with dual electronic thermistors that add 135°F (57°C) fixed-temperature heat sensing for Silent Knight SK protocol SLC loops. It uses an enhanced optical sensing chamber for broad smoke detection, rotary decimal addressing for point ID location, and includes the B300-6 detector base.
